To @ZZ whom 'it may concern.:

Be it known that I, WILLIAM O. WORTH, ofA

power-translating devices; and it has espe-v cial reference to thepower-translating devices intervening between the prime mover and thetraction-wheels 0f motor-vehicles.

My invention is susceptible of application to an ordinary road-Wagon orto a car adapted to be propelled along an iron railway-track. It mayalso be used for transmitting power to any driven device where avariable speed is required from a source of constant speed.

The drawings illustrate the application of the inventionto arailway-car, in which-f- Figure 1 is a plan view. Fig, 2 is an 'en`larged broken-away portion of an elevation, in section, of' thetranslating mechanism', taken through a practically central plane ofFig. 1. Fig. 3 is an end elevation '0f-the truck and mechanism appliedthereto. Fig. 4 is an enlarged broken-away plan view of the translatingmechanism. Fig. 5 is a detail of an enlarged traction-wheel, showing thegear-case applied thereto and the manner in which it is held inposition. Fig. 6 is a detail of one of the friction disks or wheels ofthe translating mechanism, showing the means by which the friction-Wheelis shifted in front of the face of the driving frictiondisk. Fig. 7 istaken ou a `central plane through line 7 7 of Fig." 8. Fig. 8 is anenlarged side elevation of the gear-case, partly broken away, showing aportion of the double-tapered gear-Wheel fixed to the driven shaft andthe means for changing the speed of the same. Fig. 9 is an enlargedbrokenaWay det-ail of lthe tumbling-shaft and the universal joint, insection, by which said shafts are connected together.

In all of the views the same numerals of reference indicate similarparts.

A frame for supporting the source ofpower, the translating device, andthe running-gear is provided by the side beams l and l, 2 and 2:, 3 and3 by the cross-bars 4, 4, 4", and 4C.

Journal-boxes 5 and 5L are supported on the frame and are designed tocarry the journals of the shafts or axles 7 7, upon which thetraction-Wheels 6 are fixed.

The motive power is furnished by the engines S and 8, which are designedto run, preferably, at a practically constant speed. These engines aremounted, respectively, upon the side beams 1 and 1tl and are operativelyconnected together by means of the shaft 9. They are designed to rotateat a uniform and equal speed and in the same direction with reference toeach other. Any suitable engine or motor may be substituted for thoseshown in the drawings. Driving friction-disks 10 and 10a are made fastto the shaft or axle 9. The confronting surfaces of the respectivedisksare made parallel and are prepared so as to possess a high frictional'coefficient with the driven disks. The shaft 9 passes freely through aT-shaped piece 11, in the lateral projections of which shaft-bearingsare provided for the shafts 12 and 13. Two parallel angle-iron pieces 15and l5 are fixed, respectively, to thecross-bars 4L and 4l. Near theends of these pieces, and preferably immediately over the cross-bars 4aand 4b, are erected two vertical,bearing-brackets 16 and 16a. A yoke 17,provided with a centrally-located doWnwardly-projecting piece 18,provides bearings 19 and 19a for the respective shafts 12 and 13. Theyoke17 is hinged to the vertical bearing-brackets 16 and 16a at thepoints 2O and 20a. lt is provided with downwardly-extending arms 2l and21a. A shaft 22 is carried by vthe bearings 23, 23a, 23", and

V23, which are fixed to the angle-piece 15a.

yoke 17 by means of the links 25 and 250, respectively. A yoke26`surrounds the shaft 9 and the cross-piece 11 and is provided withbearings thereon, the upper end of which is loosely bolted to thedownwardly-depending IOO which is connected to the crank-arms 24 and 24"by links 25u and 25", respectively.

The rod 22 may extend to each end of the car, and any convenient meansfor oscillating it maybe provided. The shafts 12 and 13 are provided,respectively, with splines 12 and 13a. Friction-disks 28 and 29 areadapted to be reciprocated over the respective shafts 12 and 13 and tobe positively driven by the respective splines 12 and 13: Rods 3U and 31are supported on the brackets 16 and 16 and are adapted to bereciprocated in their bearings. The rod 30 extends forward to one end ofthe car, and the rod 3l extends forward to the opposite end of the car.They may be provided vwith any means for conveniently reciprocatingthem. Each rod is pro-y vided with a rack 3()a and 31, into each ofwhich a transmitting or idler gear-wheel 32 meshes. The pivot or axisupon which this gear-Wheel rotates is stationary upon the block 33. Whenreciprocating motion is imparted to either of the rods, it istransmitted by virtue of the transmitting gear-wheel 32 to the opposingrod in the opposite direction. Each of the friction-wheels 28 and 29 isprovided With a grooved collar. An upwardlyextending fork 28 is fixed tothe rod 3l and enters the grooved collar of the friction-disk 28.V Asimilar upwardly-extending fork 295L is fixed to the rod 30 and entersthe grooved collar of the friction-disk 29. By this means thefriction-disks 28 and 29 are reciprocated upon their respective shafts12 and 13 when either of the rods 30 or 31 is primarily reciprocated.Gear-cases 34 and 34a are carried upon the axles 7 7. Each casecontainsadonble-beveled gear-Wheel 35, which islixed to the respectiveshafts b v means of a key 36. Parallel shafts 37 and 37a enter one sideof the case,find bearings therein, and carry tapered pinions 38 and 38,which are located on the respective shafts. These tapered pinions meshinto the teeth on the opposite sides of the tapered gear- Wheel 35. Theshaft 37 carries a small pinion 39, which is fixed thereto and whichmeshes into a larger gear-wheel 39, fixed to the shaft 37a. The groovedclutch-collar 40 is adapted to be reciprocated on the shaft 37 and isprovided with teeth upon the annular surface thatconfronts the taperedpinion 38,which are adapted to engage with similar teeth made integralwith the pinion 38. A similar grooved collar 40 surrounds the shaft 37and is adapted to be rotated therewith and to be reciprocated thereon.It is also provided with teeth on the surface confronting the taperedpinion 38a, which are adapted to engage With similar teeth carried bythe said pinion. arm 41 is adapted to be oscillated upon the axis, asshown, and is provided with a fork Vat each end, which enter the grooveson the respective clutch-collars 40 and 40'. A vertical rod 42 passesthrough the arm 41 and is adapted to oscillate the same. To prevent Anlthe gearcase 34 from being rotated, an arm 42a is fixed thereto and isloosely supported upon the cross-bar 4f. Tumbling-shafts 43 and 43aconnect the shafts 12 and 13 with the shafts 37 37. Universal joints 44are provided at each end of the tumbling-shafts and connecting-shafts.

The use and operation of my device are as follows:- As shown in Fig. 1,the shaft 9 may be rotated by theengines 8 and 8iL without transmittingany motion to the tractionwheels. The friction-disks 28 and 29 donot, asshown in Fig. 1, make contact with the face of either of the disks 10 or10, which is necessary for the purpose of transmitting power therefromto the respective Wheels. Looking at Fig. 3, supposing that `the shaft22 shall be rotated so that the crank-arms 24 are turned to the leftmotion will be transmitted by the respective links 25 to the arms 21,26a, and 2liL and the yoke which supports the shafts 12 13, and thefriction-disks 28 and 29 will be deflected toward the drivingfriction-disk 10 until the friction-disks 28 and 29 shall makeperipheral contact with the friction-face of the said wheel or disk. Inthat event the friction-disk 28, and thereby the shafts 12 and 43, willbe driven in a given direction, `While the friction-disk 29 and theshafts 13 and 43 will be driven in the opposite direction. It will benoticed in Fig. 1 that the respective shafts 43 are connected withpinions 38, that are located on opposite sides of the gear-wheels 35with respect to a central plane. For this reason the power transmitteddirect to the respective axles 7 will be in the proper direction topropel the vehicle in a given course. Vhen the driven disks 28 and 29make contact with the driving frictiomdisk 10a at points nearer itsextreme circumference, the vehicle will be propelled at the highestspeed consistent with the speed of the driving-shaft 9. In Fig. 4 thefriction-idlers 28 and 29 are shown in dotted lines to have been movedup to a point nearer the center of the disks 10 and 10a, so that whenthey make contact with either of the said disks while in this positionthe vehicle will be driven at a slower speed, but the power torquetransmitted to the traction-wheels is proportionately greater. Thewheels 28 and 29 are reciprocatedin position with reference to thediameter of the disks 10 and 10*L by means of the reciprocating rods 30and 3l and are caused to move coincidently by virtue of the fact thatthe transmitting-disk 32, which connects the respective rods together,will cause the opposite rodand its respective disk to move coincidentlywith the rod which has been primarily reciprocated. By this arrangementeither rod 30 or 31 may be primarily reciprocated, when the accompanyingrod will have'im parted to it asimilar motion of the same extent,whereby its corresponding disk, either 28 or'29, will be movedcoincidently and consistently therewith. When it is desirable to reversethe direction of propulsion of the vehicle, the rod 22 should beoscillated in the opposite direction, so that the crank-arms 24 willmove the oscillating system, including the frictiondisks 28 and 29, intofrictional contact with the face of the disk 10. By this means thevehicle will be propelled in a direction opposite to that which it waspropelled when the friction-disks 28 and 29 made contact with the faceof the disk 10.

When the pressure is not applied to the shaft 22 for the purpose ofoscillating it -for throwing the friction-disks 28 and 29 into contactwith either the disk 10 or 10a, the parts of the system will assume thenormal position shown in Fig. l and Fig.'2, in which the shaft 9 and therespective engines revolve idly and power is not transmitted through thetranslating device to the traction-wheels of the vehicle.

In the position shown in Fig. 7 power is transmitted to thedouble-beveled gear-wheel 35 from lthe shaft 37 through the clutch 40and the pinion 38, which is otherwise loose on its shaft, to thegear-wheel 35. The pinion 39, which is fixed to the shaft 37, is muchsmaller than the pinion 39, which is xed to the shaft 37, and thereforewhen the clutch 40a is thrown into engagement with the beveled pinion 38and the clutch 40 is thrown out of engagement with thepinion 38 then thepower will be transmitted through the. shaft 37, the pinion 39, thegear-wheel 3.9LL to the shaft 37, through the clutch 40 to the pinion38, and thence to the gear-wheel 35. Then the speed is much slower withreference to the rate of speed at which the shaft 7 will be driven, butthe torque is thereby Aproportionately increased, and while the vehiclewill be propelled at a slower speed there is a greater power availablefor propelling it over obstacles and for climbing hills. Any means bywhich the shaft 22 may be oscillated may be employed'for this purpose.
